Get and Set Cursor Positions

[Former Member]

Hi,

I have a table control and I am able to delete lines via a button I've placed on the screen;

the problem is when I delete a line the cursor automatically goes back to the top of the screen (1st field) not even within the table control.

I've been told to use get_cursor and set_cursor to solve this but not sure exactly how to use it

can anybody assist?

My code is as follows:-

PROCESS BEFORE OUTPUT.
* MODULE STATUS_0203.
  MODULE get_data_0203.

  MODULE get_cursor.      " RP 25.06.09


* This binds the table control and the table memory.
  LOOP AT gtc_ipscale INTO zrc_gui_tc_ipscale
    WITH CONTROL tc_scale_rate.
*   Obtain number of lines on the table control.
    MODULE tc_scale_rate_get_lines.
  ENDLOOP.

  MODULE modify_screen_0203.
  MODULE hide_buttons.
*
PROCESS AFTER INPUT.

* Loop at the table rows.
  LOOP AT gtc_ipscale.

    CHAIN.
*     Tranfer the screen field values to the ABAP work area.
      FIELD: zrc_gui_tc_ipscale-selected,
             zrc_gui_tc_ipscale-cost_group,
             zrc_gui_tc_ipscale-scale_id,
             zrc_gui_tc_ipscale-scale_name,
             zrc_gui_tc_ipscale-ip.
      MODULE modify_gtc_ipscale ON CHAIN-REQUEST.

    ENDCHAIN.
  ENDLOOP.

  MODULE user_command_0203.

  module set_cursor.   " RP 25.06.09

  MODULE set_data_0203.

module GET_CURSOR output.
  PERFORM get_cursor.      " RP 25.06.09
endmodule.                 " GET_CURSOR  OUTPUT

form GET_CURSOR .

data: l_fline type sy-index,
      l_curline type sy-index.


l_fline = 1.
l_curline = 3.

CALL FUNCTION 'GET_CURSOR'
 IMPORTING
   FIRST_LINE          = l_fline
   CURSOR_LINE         = l_curline
*   CURSOR_OFFSET       =
          .
endform.

MODULE set_cursor INPUT.
  PERFORM set_cursor.   " RP 25.06.09
ENDMODULE.

form SET_CURSOR .

data: l_fline type sy-index,
      l_curline type sy-index.

l_fline = 1.
l_curline = 3.

CALL FUNCTION 'SET_CURSOR'
  EXPORTING
    first_line          = l_fline
    cursor_line         = l_curline
*    cursor_offset       =
* IMPORTING
*   EDIT                =
          .
endform.

Chane code :

GET CURSOR in PAI and SET CURSOR in PBO.

Thanks for that you are a star.

Was going around in circles.

+ I need to clear the cursor in the parent form.

Thanks once again.

full solution is as follows:-

PROCESS BEFORE OUTPUT.
* MODULE STATUS_0203.
  MODULE get_data_0203.
 
* This binds the table control and the table memory.
  LOOP AT gtc_ipscale INTO zrc_gui_tc_ipscale

*   Obtain number of lines on the table control.
    MODULE tc_scale_rate_get_lines.
    MODULE  set_cursor.   " RP 25.06.09 - Note has to be within loop.
  ENDLOOP.
 
  MODULE modify_screen_0203.
  MODULE hide_buttons.
*
PROCESS AFTER INPUT.
 
* Loop at the table rows.
  LOOP AT gtc_ipscale.
    CHAIN.
*     Tranfer the screen field values to the ABAP work area.
      FIELD: zrc_gui_tc_ipscale-selected,

             zrc_gui_tc_ipscale-scale_name,
             zrc_gui_tc_ipscale-ip.
      MODULE modify_gtc_ipscale ON CHAIN-REQUEST.
    ENDCHAIN.
    MODULE get_cursor.      " RP 25.06.09 - Note has to be within loop.
  ENDLOOP.
 
  MODULE user_command_0203.

module GET_CURSOR output.
  PERFORM get_cursor.      " RP 25.06.09
endmodule.                 

form GET_CURSOR .
   IF g_cursor_field IS INITIAL.
    GET CURSOR FIELD g_cursor_field LINE g_cursor_line.
  ENDIF.
endform.

MODULE set_cursor INPUT.
  PERFORM set_cursor.   " RP 25.06.09
ENDMODULE.

form SET_CURSOR .
  IF g_cursor_field IS NOT INITIAL.
    SET CURSOR FIELD g_cursor_field LINE g_cursor_line.
  ENDIF.
endform.


** In the parent form within the PBO clear the cursor.*
PROCESS BEFORE OUTPUT.

  MODULE clear_cursor.    " Only clear in the parent PBO

module CLEAR_CURSOR output.
PERFORM clear_cursor.
endmodule.

FORM clear_cursor .
  CLEAR g_cursor_field.
  CLEAR g_cursor_line.
ENDFORM.

In PBO, write the following code :

set cursor field '<table name>-<fieldname>' line v_line.

where v_line is the row number where you want to set ur cursor.

Eg. - The following code sets the cursor to the 3rd row of the field END_DATE in the tablecontrol.

controls: tabctrl type tableview using screen 9000.

data: v_line type i value 3.

set cursor field 'ZZZ_TAB1-END_DATE' line v_line.

where tabctrl is the table control,

ZZZ_TAB1 is the DDIC table structure associated with the table control in the screen,

END_DATE is the field of the table ZZZ_TAB1.
